Description

ISOVUE 250

Participants were injected at least once in 1 of the following 3 locations: aortic bifurcation (injection rate 8-10 mL/s, total volume 15-20 mL), iliac arteries (injection rate 5-6 mL/s, total volume 10-12 mL), or superficial femoral artery (injection rate 3-5 mL/s, depending on diameter and condition of artery, total volume 8-12 mL to view only thigh, 10-15 mL to view calf as well, 20 mL for full runoff to foot).

VISIPAQUE 270

Participants were injected at least once in 1 of the following 3 locations: aortic bifurcation (injection rate 8-10 mL/s, total volume 15-20 mL), iliac arteries (injection rate 5-6 mL/s, total volume 10-12 mL), or superficial femoral artery (injection rate 3-5 mL/s, depending on diameter and condition of artery, total volume 8-12 mL to view only thigh, 10-15 mL to view calf as well, 20 mL for full runoff to foot).
